Conditional formatting for Gantt chart bar based on another cell

I looked through the help topics and tried copying several other formulas, but can't get this to work.

I'm creating a Gantt chart and would like to add a conditional formatting rule where the Gantt chart bar (which is currently blue) turns red if the "Lead" for that row is "Milestone".

Any help is appreciated!
